BaFe2O4 nanostructures have been synthesized through a simple sonochemical reduction approach. X-ray diffraction characterization suggested that the product consists of cubic phase pure BaFe2O4. The as-prepared products were also characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). An X-ray energy dispersive spectroscopy (EDX) study further confirmed t...

The effects of stoichiometry factor on the magnetic and structural properties of perpendicular barium ferrite thin films with composition of BaO (Fe2O3) were systematically investigated. Within the range 2 2 6, the -axis for barium ferrite thin films can be oriented perpendicularly by the use of Pt underlayer and with optimized processing conditions. Perpendicular -axis orientation becomes wors...

this review reports recent advances in metallic nanostructures based electrochemical sensors. interesting aspects of nps include size and shape-dependent interatomic bond distances, melting points, chemical reactivity, and optical and electronic properties. the small size of metallic nanostructures has allowed nanoscale electrochemical processes to be probed. electrochemical characteristics can...

cupper oxide structures with a variety of novel morphologies are synthesized using cupper foil as substrate via a solution route. the structure, morphology and phase of the as-synthesized nanostructures are analyzed by various techniques. sem images show gradual development of hierarchical structures of copper oxide with different morphology. in order to study the effect of reaction time and te...

in this pepper fe2o3 nanoparticles were synthesized via a fast microwave method. then fe2o3-tio2 nanocomposites were synthesized by a sonochemical-assisted method. the prepared products were characterized by x-ray diffraction pattern, scanning electron microscopy and fourier transform infrared spectroscopy. the photocatalytic behaviour of fe2o3-tio2 nanocomposites was evaluated using the degrad...

tellurium nanostructures have been prepared by physical vapor deposition method in a tube furnace. the experiments were carried out under argon gas flow at a pressure of 1 mbar. tellurium powder was evaporated by heating at 350°c and 430°c and was condensed on substrates at 110–250°c, in the downstream of argon gas flow. the products were characterized by field emission scanning electron micros...
